MACRS table needed for this problem. Mars Inc. is considering the purchase fo a new machine which will reduce manufacturing costs by $5,000 annually. Mars will use the MACRS accelerated method to depreciate the machine, and it expects to sell the machine at the end of its 5-year operating life for $10,000. The firm expects to be able to reduce net working capital by $15,000 when the machine is installed, but required working capital will return to the original level when the machine is sold after 5 years. Mars' marginal tax rate is 40%, and it uses a 12% cost of capital to evaluate projects of this nature. If the machine costs $60,000, what is the NPV of the project?
